Answer:
The first one
Step-by-step explanation:
On a graph, if the line starts at the origin, where the 0 is, which is the center in this case, it is proportional
On a table, if the numbers all the have the same rate of change, which is y/x, then it is proportional
Answer:
the first one is -4.6
Step-by-step explanation:
taking 2 to the other side ⇒
= 5 x 2
3x=10
taking 3 to the other side ⇒ x =
x = 3.34
So the equaiton is
number of nickes=n
number of quarters=q
if you have 1 quarter then you have 25 cents so we will represent like this
25q
and nickles is 5n
14.50=1450 cents
so
25q+5n=1480
q+n=88
subtract q from both sides
n=88-q
subsitute into first equation
25q+5(88-q)=1480
25q+440-5q=1480
add like terms
20q+440=1480
subtract 440 from both sides
20q=1040
divide both sdies by 20
q=52
there were 52 quarters
25(52)+5n=1480
1300+5n=1480
subtract 1300 from both sides
5n=180
divide both sides by 5
n=36
there were 36 nickels
nickles=36
quarters=52
The 6 in 216 is in the ones place.
